GE-AS-TE GLASSY SYSTEM - ATOMIC DISTRIBUTION MODELS

Atomic structure models were generated for the semiconducting glassy alloys Ge//xAs//0//. //2//0Te//0//. //8//0// minus //x (x equals 0. 05, 0. 10), from short-range order information given by the corresponding radial distribution functions, obtained from X-ray diffraction intensities. The Metropolis Monte Carlo random method was used in the building of the models, and the fact that Ge atoms can be four- and three-coordinated has been taken into account. The structural parameters obtained from the models agree with those given in the literature for similar alloys.
